Layer Details
White fibre fillings
A layer of white fibre fillings sits in the quilted cover, above the foam interior. It adds a little surface cushioning on what is otherwise an extra-firm mattress.
Advanced reflex foam core
The core is advanced reflex foam, designed to conform to your body's contours and spread your weight evenly. For you, that means fewer pressure points, while the overall feel stays extra firm.

Key benefits
- Real room to spread out alone: At 120cm across, the UK small double is 30cm wider than the UK single, which means a solo adult can sprawl without paying for width they never use.
- Fits rooms a full double crowds: It is 15cm narrower than the UK double, and that margin often decides whether a door still clears or a wardrobe stays.
- Boxed delivery suits tight spaces: The Halifax arrives compressed and rolled, so it goes up a boxy loft staircase or through a studio flat hallway without a struggle.
- Sensible for occasional guests: Couples can share a small double for a weekend visit comfortably enough, making it a practical choice for a guest room that hosts a few times a year.
- Standard 4ft bedding and frames: Small double is an established UK size, so fitted sheets and bed frames are easy to find rather than specialist purchases.
This size suits you if...
You sleep alone and have outgrown a single but your room can't spare the width of a full double, you're furnishing a box room, studio or loft conversion where every centimetre beside the bed matters, or you need a guest bed that couples can share a few weekends a year without dominating a small second bedroom.
Consider another size if...
You share the bed every night, because 120cm is a little tight for two people long term. We'd recommend the UK double instead, or the UK king if your room allows at least the extra width.

FAQ's
What size is the Highgrove Halifax small double?
The UK small double measures 120 x 190cm, or 4ft x 6ft 3in. That's the same length as a UK single and UK double, with the width sitting between the two. We suggest a room of at least 2.4m x 2.8m to leave walking space around the bed.
Is the Highgrove Halifax small double big enough for a couple?
For occasional nights, yes. Two adults can share 120cm of width for a weekend stay without much complaint. As an everyday bed for a couple it's a little snug, since the UK small double is 15cm narrower than the UK double. Nightly sharers would be happier sizing up.
Will the Highgrove Halifax small double fit in a box room?
Usually, and it's one of the main reasons to choose this size. Allow at least 2.4m x 2.8m of floor space so you can still open drawers and move around the bed. Because the Halifax arrives rolled in a box, getting it into an awkward room is straightforward too.
How much more space does a small double give one person than a single?
The UK small double is 30cm wider than the UK single, which you feel every night as room to roll over or sleep diagonally without an arm hanging off the edge. It suits a teenager who has outgrown a single but whose room can't take a bigger frame.
What bedding fits the Highgrove Halifax in a small double?
You'll need small double (4ft) fitted sheets, which are a standard UK size and widely available rather than a specialist order. A standard double duvet works well on top, giving a comfortable overhang on both sides of the 120cm mattress.
